Difficulty: Easy
Correct Answer: constant current region
Explanation:
Introduction / Context:
JFETs are voltage-controlled devices widely used for amplifiers. Their operation is divided into cutoff, ohmic, saturation (also called constant current) regions. Amplification occurs only in a particular region.
Given Data / Assumptions:
Concept / Approach:
For amplifier action, the device must have drain current controlled primarily by VGS, not by VDS. This is the saturation region, also referred to as the 'constant current region.'
Step-by-Step Solution:
Verification / Alternative check:
Amplifier bias points are always chosen in constant current region for linearity.
Why Other Options Are Wrong:
Common Pitfalls:
Final Answer:
constant current region
